My home was constructed 4 years ago. We have 5 standard smoke alarms and 2 combo smoke/CO detectors in the house. They are all hardwired to the home power. All alarms activate whenever a single unit activates.
The problem, whenever we have relatively close lightening strikes, the alarms go...

SUCCESS - with a 500VA power conditioner. Wired 120vac from exisitng 300VA control XFMR through new power conditioner from Sola and fed 120vac for the system. Works like a champ. Special thanks to Laplacian for the early suggestion.

One last thing to note...
Compact is limited to a single ethernet port. Controllogix can have several Ethernet cards in the backplane to isolate networks (drives, HMI, plant floot, etc.)

I've had some decent results with PROFACE units. It has been a couple years now so it is hard to recall, but one thing i seem to remember was they may have been slightly limited in their I/O count. I'm sure with some distributed networking you could remedy that.

The "Chattering" in this instance I am referring to could best be described by the result if we were firing the motor starter rapidly from an output so fast that the motor doesn't get a chance to turn.
Power System - seems the installation is a little goofy in my opinion...

The 480 VAC feed from the transformer is tapped high and is around 497 volts. This has given the control xfmr about 130 VAC before startup. Still diping to 105vac. I bypassed the control xfmr with an extension cord from an external building outlet at 124vac with similar...
EthernetIP was developed by Rockwell Automation (Allen-Bradley) about 10 years ago or a little more. It has been released to a national standards management board however it has taken a while to migrate beyond the AB world. Several non-AB automation vendors now offer compatible devices or PLCs...
